A paper in Physical Review Letters has been retracted for “overlap” with two other previously published papers.

The notice isn’t available online yet, so we got in touch with American Physical Society (APS) editorial director Dan Kulp for more information. Here’s what he told us about “Anomalous melting scenario of the two-dimensional core-softened system”: Read the rest of this entry »

A paper on photonic quantum walks has been retracted over a theoretical disagreement.

The notice is also paywalled, which the editorial director has assured us is a mistake that is being corrected.

We sent the COPE guidelines on retraction to the American Physical Society, which publishes Physical Review Letters. Editorial director Dan Kulp told us the paywall was the unintentional consequence of a web redesign, and that they are in the process of restoring public access to “all Errata-types, including Retractions.”

The authors of a paper in Physical Review Letters have retracted it, after another researcher pointed out a mistake.

F. Sattin and D.F. Escande write in the notice for “Alfvénic Propagation: A Key to Nonlocal Effects in Magnetized Plasmas” (which is behind a paywall) that after the paper was published, they “we became aware of a fundamental error in the normalization of our equations.” Excerpt: Read the rest of this entry »

Just six days later, after hearing from a physicist in China, Pavičić — who is also affiliated with Harvard’s physics department — submitted a correction, which ran on the journal’s site in November. The correction begins: Read the rest of this entry »

Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.

But one researcher may have allowed his enthusiasm for graphene to get ahead of him. He and his unwitting co-authors have now lost two papers thanks to that enthusiasm. Read the rest of this entry »
